Experiment - Version III

... Move the droplet into the central area of the grid before making the next change to reduce the probability of losing the droplet. Press to restore this standard voltage and measure the velocity of the droplet under the
influence of both gravity and the standard electric field (vt). Use the zoom ...

Chapter 9. Modeling Flows in Moving Zones

... ∂Ω neglects the ρ ∂t × ~r term, so it cannot accurately model a time-varying angular velocity using the relative velocity formulation. For flows in rotating domains, the equation for conservation of mass, or continuity equation, can be written as follows for both the absolute and the relative veloci ...

High-electric-field limit for the Vlasov–Maxwell–Fokker

... is large compared to the thermal velocity, the other physical parameters being fixed. The high-field limit of the VPFP system can be addressed by appealing to usual compactness methods; however, constraints on the space dimension appear, due to the singularity of the convolution kernel. It turns out ...

In turn, the equation for (E) can be further reduced to other well-studied linear partial differential equations, such as Thomas-Fermi or London equations, whose known solutions can be used to obtain exact solutions for 2D current flows in nonlinear co ...
